This page is not veterinary advice. Paw Multiverse is not a veterinary practice. We cannot examine, diagnose or treat your animal. There are no doses here, no portion sizes, no feeding amounts, no exercise durations and no treatment steps, on purpose. If your animal has changed in a way you cannot explain, ring your vet or your nearest emergency clinic.
This page used to carry a vaccination schedule. It does not any more, and that was deliberate. Until 5 August 2026 this post named specific vaccines and gave ages in weeks. Both were removed, because this site does not publish a dose, an interval, a minimum age, a product name or a schedule for anything, and a vaccination schedule is the clearest example of the kind of instruction a web page has no business handing to a stranger.
What follows is everything that can honestly be said about puppy vaccination by somebody who cannot see your puppy: what the schedule is for, who writes it, why it is a series rather than one visit, what is genuinely uncertain, and what to ask the person who can see your puppy.
Why there is no schedule here
A vaccination schedule is a clinical decision. It depends on where the animal lives, what it will meet, what its mother was vaccinated with and when, what products the practice stocks, and what the local disease picture looks like. Those are not things a reader can supply to a web page and they are not things a web page can infer.
The published schedules are written for veterinary surgeons. The World Small Animal Veterinary Association vaccination guidelines, in the 2024 edition, describe themselves as providing “practical advice to veterinarians on optimum vaccination practice”. Read on 5 August 2026, the WSAVA page records the current guidelines as published on 26 March 2024 and updated on 29 July 2026. They are a professional document with a professional audience, and lifting a table out of them and putting it on a consumer page strips away every caveat that made it safe.
So this page names the source and stops. If you want the schedule, the person to ask is the veterinary surgeon who will be giving it, and the reason to ask them rather than us is that they can adjust it and we cannot.
Why it is a series and not one visit
This part is mechanism, not instruction, and it is the single most useful thing a puppy owner can understand.
A puppy is born with antibody it did not make. It comes from the mother, and while it is present it protects the puppy against the same things the mother was protected against. It also gets in the way. The European Medicines Agency reflection paper on maternally derived antibodies, reference EMA/CVMP/IWP/439467/2007, last updated 18 March 2010 and read on 5 August 2026, exists specifically to tell manufacturers how to demonstrate “to which extent MDAs may have an impact on the efficacy of vaccines when administered to animals at an age at which maternally acquired immunity is still present”.
Read that again, because it is the whole problem in one sentence. Maternal antibody protects and interferes at the same time. It fades, but it fades at a rate that differs between litters and between individual puppies in the same litter, and there is no way to look at a puppy and know where it has got to.
Why a puppy gets more than one visit
===================================
at birth antibody from the mother is present
it protects, and it blocks vaccine response
over time that antibody fades
the rate differs between puppies
the problem nobody can see when it has faded
the answer more than one dose, spaced out, so that at
least one of them lands after the block has
gone and before the puppy is exposed
the numbers how many, how far apart, and from what age
are the veterinary surgeon's decision
they are not on this page
That is why the series exists. It is not a booster in the ordinary sense and it is not a top up. It is several attempts at hitting a window whose position nobody can measure directly in a routine setting.
What the different kinds of vaccine actually are
The MSD Veterinary Manual page on types of vaccines for animals, read 5 August 2026, sets out the categories without reference to any species schedule. Vaccines containing living organisms “tend to trigger the best protective responses”, because, in the manual’s words, “living viruses from vaccines, for example, infect host cells and grow briefly. The infected cells then process the viral antigens, triggering a response dominated by cytotoxic T cells”.
Killed organisms and purified antigens work differently and produce a response dominated by antibody. The manual notes that these “may require multiple doses and also require the use of adjuvants to maximize their effectiveness”, and that adjuvants “may, however, cause local inflammation, and multiple doses or high doses of antigen increase the risks of producing hypersensitivity reactions”.
That is a real trade off, stated by the publisher, and it is one of the things a veterinary surgeon is balancing when they choose a product. It is also why “which vaccine” is not a question with one right answer.
If something goes wrong afterwards
In the United Kingdom, suspected problems with an animal medicine are reported to the Veterinary Medicines Directorate. The GOV.UK page on reporting a suspected problem with an animal medicine or microchip, last updated 18 December 2024 and read on 5 August 2026, is written for the public as well as for professionals.
It covers more than you might expect. Reportable problems include “times when a medicine has not worked”, “reactions and side effects already listed on the product’s packaging”, problems where a medicine was used contrary to instructions, and human reactions to an animal medicine. Reports can be made online, on a paper form obtained from the VMD, or indirectly through your vet or the manufacturer. The page states that “the VMD will use reports to help check if medicines continue to be safe and work as expected”, and warns that “you will not get updates about your report”.
The point of including this is not to alarm anybody. It is that a reaction which is already printed on the packaging is still worth reporting, and most owners do not know that.
Nothing on this page tells you what a normal reaction looks like or how long one should last, because that is exactly the judgement that needs a professional. If your puppy is not right after a vaccination, ring the practice that gave it. See the emergency vet page if it is out of hours.
What to ask, printable
Questions for the appointment. Not instructions, and not a schedule.
What we could not source
- The WSAVA guideline document itself. We read the guidelines landing page and its stated dates and audience. The full document is a download and we have quoted only what the page itself says, rather than reporting contents we did not read.
- Any UK figure for vaccination uptake in puppies. Not obtained from a publisher in a dated, readable form.
- Any figure for how often adverse events are reported after vaccination in dogs. The VMD publishes pharmacovigilance material; we could not obtain a current, clearly dated figure we were willing to quote.
- Any statement about duration of immunity. This is the question owners most want answered. We could not source it in a form that would be safe to publish without a schedule attached, so it is not answered here.
- Anything about titre testing. Same reason.

The same refusal to print numbers, applied elsewhere: the food reference explains why there are no feeding amounts anywhere here, and the breed pages, for example the Labrador Retriever page and the Beagle page, name the figures they decline to reproduce and why.
If you have just brought a puppy home, the pages likely to be useful are switching food safely, the poison control directory, what to do if your pet ate something and finding an emergency vet. For spending, the cost hub and the vet costs guide. The cat version of this page is the kitten vaccination page.
